The main object of this invention is to provide a simple device for propelling a small craft, said device having a shaft similar to an oar.

I attain these objects with the device illustrated 5 in the accompanying drawing, in which- Fig. 1 is a perspective view, from the rear, of my rowing device.

Fig. 2 is an enlarged perspective View of the car securing device, shown in Fig. 1.

The numeral 5 designates a supporting base having an upright 6 which is braced by rope guys 1 and 8. Secured to the top of the upright by fastenings 9 is an oar securing element H having U-shaped hooks I2 and I3, the ends of 15 which hooks are in axial alignment with each other. These hooks are adapted to receive eyes l4 rotatably mounted in the upper ends of oars I6. At I1 I have shown a leather wedge adapted to be inserted under compression between the 20 hooks I2 and I3 and between the eyes [4 and the free ends of the hooks. This leather wedge holds the eyes 14 in contact with the lower portion of the hooks yet permits the eye to rotate around the hook or to swing upwardly or downwardly, 5 thus permitting of universal movement of the car. When it is desired to remove the oar the wedge is removed and the eye can then be disengaged and removed through the opening A. It will thus be seen that I have produced a very simple arrangement for mounting cars of this type.

Having thus described my invention, I claim:

1. Means for propelling a boat comprising, in combination, an oar, an upright support, a hook fastened to said support, and an eye rotatably mounted in an end of said oar and engaging said hook whereby said oar is permitted universal movement.

2. Means for propelling a boat comprising, in combination, a pair of oars, an upright support, a pair of oppositely disposed hooks fastened to said support, an eye rotatably mounted in an end of each oar; each eye engaging one of said hooks, and a resilient wedge interposed between said hooks and frictionally held therebetween overlying the eyes of the oars to prevent dislodgment of the eyes from the hooks during universal movement of the oars.
